Requirements for milling hardened steels
Tough Tools. When milling materials from 50 to 60 HRC, not just any cutter will do. Not only is the workpiece very hard, but to reduce thermal fluctuations on the cutting tool, machining is typically done dry. For this, you need tough tools. One company offering such tools is SGS Tool Co., Munroe Falls, Ohio.

Carbide End Mills | McMaster-Carr
A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them to provide fast cuts, smooth finishes, and long tool life.

How to do milling in different materials - Coromant
Unlike milling in most other materials, coolant is always recommended to assist in chip removal, to control heat at the cutting edge and to prevent the re-cutting of chips. High pressure coolant (70 bar (1015 psi)) applied through the spindle/tools is always to be preferred instead of an external supply and low pressure.
